nice.
personally, I still prefer buf[0], because I think it's more readable.
It's clear for the reader that the struct will be allocated larger
than sizeof(struct foo), while with macro, that's not immediately
obvious.
btw, anybody can list compilers that reject buf[0] (inside struct)? MS
visual C doesn't seem to complain either.
